The Buick 400, 430 and 455 were all the same block, and that block was 1.5" wider than a SBC, but only 30 pounds heavier. Considering a BBC was 900 pounds, and a max of 454 CID, the Buicks were much lighter, and the 455 had more displacement... I put a "mildly" improved 455 in my first car (1968 Impala 2-door Custom) in high school. It came stock with a THM-400 and 2:56 gears in the punkin. She got a mid-grade RV cam, dual exhaust and an 830 thermo-quad toilet. At 4,280 pounds with 5 gallons in the tank, that 455 would light up both rear tires at 25 mph and keep smoking until I got my foot out of the carburetor. It also got 12 mpg at 80 miles per hour between Montana and Kansas. What an American icon.

Back in 1970 Buick GS 455 Stage 1 was the torque of the town!!!! I got mine in '74. It was a G.S Stage 1,4spd 3.42:1 posi. Power steering & front disc brakes, & A/C. Aftermarket wasn't there for the G.S. all I got was a fiberglass fan, & ' vette sized hi performance radials. As hard as I drove, the G.S. NEVER left me stranded. I, would ride w/6ppl, (bench seat). Stupid me got spit for it on trade in '76. Then the 455 on my 2dr Landau 225 had no where near the power. But,I got just about every option, I fell in love again with Buick. When better cars are built, BUICK BUILT THEM 🇺🇸♥️

Heavier than most muscle cars, but faster than most. The GSX 455 was a monster. One of my favorites.

I'm So Proud To Say That I'm The Son Of a PONTIAC and BUICK Dad That Sold Both Brands From 1964-2008 - Love That He Sold Many Of a G.T.O. and Trans Ams, But I Really Have a Special Place In My Heart For BUICK's Torque Monsters From 1968-72 Stage 1 V-8s!!!

I'm typically a Mopar guy when it comes to muscle cars...but this Buick is definitely one of my all time favorite muscle cars from GM. My top 5 GM muscle cars: 1. 69 Camaro ZL1 2. 69 GTO Judge Ram Air IV 3.70 Chevelle SS 454 LS6 4. 70 Buick GSX 455 Stage 1 5. 73 Trans Am 455SD

I can see myself behind the wheel of this car I never thought much about a Buick as a muscle car but I would definitely take this one

The term "Hemi Killer" became synonymous with the 1970 GS Stage 1 after GSCA Founder Richard Lasseter walloped a braggart with a 1970 GTX Hemi and also his friend in a 1970 Hemicuda with his Stage 1 the same day in Dec. 1984 for the March 1985 issue of Muscle Car Review. Richard's GS was driven 275 miles down to the Gainesville (FL) Raceway to beat those two Hemis!

I prefer this beauty in Apollo white......probably because that's the color Dad had. I can remember jumping around in the back seat and he'd punch it to sit me down right fast, and glare at me in the rear view mirror....lol. Mom pestered him to trading it for a luxury Riviera in 1976 or '77.....He loved him some Buicks as a lot of Dads did back then.

One of the fastest musclecars and rare to find in good condition

The GsX and the Olds 442's had some serious torque, talk about having to weld your seat brackets to the floor.

One of the best muscle cars I've ever rode in

I remember when these came out I was not very impressed with them.....Buick....funky paint job....what the heck. Then.....a 455 GSX ate up my Roadrunner at a stoplight.....and again....you get the picture. Totally had to re-think my idea of Buick....

We found a 70 in the junkyard couldn't be fixed so we put the 455 in a nova wow! we were pulling hi 11s in the quarter mi.

straight up tire fryer!!! what's not to love? ☆☆☆

Easily my favorite muscle car of all time. Thank you for a great trip.

Thanks for the cool video. I like seeing sporty Buicks since there's nothing cooler than seeing a fast car from a brand that isn't known for being fast. In a way, this GSX is almost like a grandfather to the Regal T-Types and Grand Nationals of the 80s.

My frend had one I drove it I couldn't believe the power. I had a 70 GTO with a 455HO the GSX was more powerful and the perfect sleeper if you race it your going to lose

They were the true definition of a "badass" muscle car.

Oh yeah. It’s s stock GSX with the 455 Stage 1 with 4 speed. Being 65 years old and still living in the Motor City area, I have seen a ton of muscle that guys still have stored in their garages at their homes. That Buick is an absolute monster beast and I would spend the $300K to buy one. Been looking for years and can’t find 1971 with a 4 speed anywhere even at auctions. Nice video for sure!

I rebuilt the engine in one of these (dealership) back in the late seventies. Driving gently while testing the fresh build, I lit up the tires at 70mph without shifting down (automatic). Scary ride.

Find and show a FULL FLEDGED Stage 2!! Yessssss....2!!!

I sooooo regret not paying better Attention to these old cars. I was only 5 when this came out, but they were still plentiful. The things I've let slip away. Superbird, went to scrap. A 70 Chevelle SS for $1,200, in great condition. The 428 SCJ a guy give me. I didn't realize what I had. I have a long list of Super Sports, Nova to Impala. I had a 66 and 65 Impala SS. One of my biggest regrets is, a cougar. My dad and I went to a small Junkyard almost every Saturday. One Saturday, I saw a Cougar. I always liked the Cougar over the Mustang. The front clip was set off, and the car was in great shape. It was around 79 The car was only 11-12 years old. I was 14 years old. Interior great. Motor and Trans was in the barn the guy said. Big block 4 speed. I ask my Dad, "Who's Dan Gurney?". The man priced me the car for $500. He said the engine ran great. But pop said "Nope! Too Fast!" End of subject. But I've passed so many great cars up. They were plentiful then. You could buy a Plymouth or Dodge for a few hundred. Often, people would give them to you if you got it out of the yard.

One of the most beautiful cars ever made. I’ve seen GS’s; but GSX never. Yellow and black is the perfect color combo. If I had a choice between a 454 Chevelle and the GSX; I’d chose the Buick all day.

As a teenager I remember seeing a Buick GSX for sale in the local auto trader for around $4000.00. It wasn't a big block car as it had only the 350 engine but it was still a very very nice cruiser. I ended up picking up a stock midnight blue 1973 Formula 455 and rebuilt the engine since the car was already repainted with a good paint job. Back in the 80s the police didn't harass the local kids for street racing as accidents were very few and far between.

This is the greatest car ever to lay down rubber.

Hey Kevin I'm glad you mentioned other muscle cars out there because some of the most popular ones we know of there are other ones that people never talk about I'm glad you introduced this

I had never noticed before, but it was sold at Marquardt Buick in Barrington (IL), my hometown. They are still around. I may have seen this beast back in the day.

They look good next to a 1969 Hurst/Olds. And a Pontiac Judge. GSX With a nice LS 6 Chevelle for comparison. 4 Kings! Very similar,very different.

Beautiful car! I had a 69 Buick GS 400. It was a great car. I miss it!

Of the Brothers collection, this too would be my one choice take home car. Without a shred of second thought.

This is going to be one of the first cars I purchase when I hit the lottery

I really like this car because it is actually high sought after the collector car market in today's world.

I guess you could call me a "GM guy", and in particular I am a "Chevelle guy". Chevelles are the muscle cars I know the most about, and I've owned more SS 396 or 454 Chevelles than any other make or model of muscle car throughout my life. With that said, I have ALWAYS loved the look of the 1970 Buick GS. I always thought that it looked like a more sophisticated 1970 Chevelle SS...which...actually makes perfect sense because that is essentially what it was supposed to be as a Buick muscle car. But just the overall design of the '70 GS really appeals to me and I've long thought about buying one. I'm not a big fan of the flashy GSX and really am more interested in a 1970 GS 455 or a Stage 1. I came VERY close to buying a BEAUTIFUL 1970 GS 350 car that was on my local Craigslist maybe 10 years ago. It was one of the cleanest muscle cars I've ever seen on Craigslist and I think they were only asking $14,000 for it. I'm not really into small block "muscle" cars and that is why I never called about it but boy did I come close. I figured that even if it was "just" a 350 car, for $14,000 I could buy it and drive it everywhere all the time without really worrying about it. Looking back on it now, I wish I HAD bought it because I even liked the color and options. It was gold with a brown interior and I LOVE the Earth tones on muscle cars of this era (of my collection, my baby is my 1969 Chevelle SS 396 4-speed that is Burnished Brown with a white (parchment) bucket seat interior and NO center console). It also had buckets and a center console with the automatic trans. It was just a really nice-looking car and if it had been a 455 car, I would've bought it in a heartbeat. I do have to say that I actually learned something from this video. I knew that there was the "base" 455 engine and the Stage 1 (and dealer-installed Stage 2) engine available in the regular Grand Sport but I thought that ALL of the GSX cars were Stage 1's. I truly had no idea that you could get the "base" 455 engine in the GSX! The only reason why I really am not a big fan of the GSX while I LOVE the 455 Grand Sport is because of the colors. I just don't understand why they decided to make only two colors available on the GSX, and why they would limit those two colors to just white and yellow is something I understand even LESS. Neither color really appeals to me at all. I do own a yellow Chevelle (my 1972 SS 402) but that shade of yellow is not that really loud, bright shade of yellow, it is a more cream-colored shade...which is probably why the official color name from GM was "Cream Yellow", paint code 56.

Love your muscle car vids man... Thank you for your efforts

Burning around parking lots in a hot rod brings back memories of being young and stupid with horsepower. Still am.😄.

The low end torque of the Buicks was wild. Definitely set your butt back in that seat on launching it. I had a 71 Buick skylark Buick 350 which was dependable and rode like a Cadillac . I blew the 10 bolt differential out and ended up putting a 12 bolt posi trac from a wrecked Buick custom skylark. With a thermo quad 4 barrel carburetor I could burn the tires off in all 3 of the automatic transmission. I never had issues with anything really on the car. They were great underated cars because I raced dodge and Chevy and ford's and smoked them all. Some with built engines .

Definite like for bringing me to school on the stage 1 block.. Thanks for the great video as I'll be watching y'all from now on.

A cringe-worthy memory; My childhood still embarrasses me. My father took our family to a car show in the sixties and as a car crazy child, I had been pouring over car magazines, studying up on everything available at the time so I knew more than I ought to, I guess, when I sought out a Chevrolet car salesman at the show, to tell him I had just read that GM's level of quality started at the top with Cadillac then Buick, then Oldsmobile, Pontiac, with Chevy at the bottom, and asked him if he knew that. Well, I know now, someone probably should have slapped my smart a** little mouth but I remember a depressed, sad look on the man's face as he said, "Yeah, I guess", and slowly turned and walked away. I bet I really made his day.

Great stuff. What a collection!

Another great episode!

In 1975 I was @15 at that time, saw a GSX (Saturn yellow) waded-up sitting in a junkyard near Culpeper, Va. It was bad.......... as the roof was caved sideways like it hit a tree at speed crossed-up. I went over to look and indeed it was a 4-speed car. I knew even then that it was very rare, the yard had removed the engine, but it was still there inside the building on premises. On the trunk lid was the emblem from the local Buick dealer. So it was bought AND wrecked locally! I didn't know how low the production numbers were until much later. Although the car would have been a huge project needing a donor car to complete, I always wonder if someone did save it.

Love the color

Yep, killer. The GS was someting i learned in the late '70s. This rules!

I had a Mustang Mach 1 SCJ and I ran one of these . Traction bars were a must. That car caught rough pavement and almost jumped on top of me . All big blocks had that problem. If I saw they didn't have them they were toast. I used to rev up and get them to just sit and spin . I'd just go from first to third and look for them in the rear view 😜❗

My very first car was that Buick Gran Sport pictured in the advertisement in this video. Mine was white with a black top, 4-speed. I bought it in 1970 when I was 18 years old. It was a California car so it looked terrific.

Loved my 71 Buick in high school although that was in 77

Amo demais este canal. Mesmo não entendendo nada de inglês eu adoro esse canal. I love you car antigo

Torque is everything

Man that is a nice car. I wish we could go back to the 70s.

Dang.. beautiful car. I have a 70 chevy c10. Its got a built 350. Getting ready to drop a even more built 350 in it. 70 was a speacial year for factory high performance vehicles. Am Blessed to own a 70.

Beautiful 👍🏻🇺🇸

These are worth HUGE money now!

Awesome car 🚗

there was a Stage II version, not many were made only about 25 or so. bought mine new it was 6 months too get it , had to special order it !!! the stage II came intake in the back seat in a box with the heads! lost it in a house fire !

The most torque of any of the big blocks. Great car. 👍

The only thing better then seeing one of those as a kid was surperman getting out of one. Again nailed it To the moon.

One day ima buy one of these torque monsters! Or atleast build a tribute out of my current 72 skylark

I rank on GM products today but have complete respect for their vehicles around the mid 1960's to early 70's. Everything division clicked.

Cool and good for Buick

GSX ON THE LIST!

it's one spiced Buick how ever its up to the challenge.

I have exactly the same at 1/24 scale but i want this car at 1/1 for sure..

Can anyone explain WHY the Buick 455GS motor was so damn powerful compared to other comparable engines??...(Especially the Stage 1) Compared to the HEMI, 454, 429, etc, the specs on the Buick don't seem so outstanding. So WHAT EXACTLY makes them so strong? Was it really just low/mid torque? I had a '71 GS and it felt so much more powerful than my Ford 429. Buick had some serious secret sauce.

Your crazy if you really think this car's 455 was only producing 360 HP. They were purposely underrating the HP on these models, as was every other Muscle car made from 67 through 1970. The Buick GS Stage 1 and the GSX were producing over 420 HP when checked on the Dyno. It had a faster time in the quarter mile than the 1970 426 Hemi Cuda. The Buick GS Stage 1 was one of the fastest cars out on the street.

Every one that talks about the 70 GS always comments on the hood scoops and say the same thing, that they don't do much. But that simply isn't true. Nothing but a big Pro Stock scoop does much to force any air in but in reality the air speed moving into the engine is way faster than any hood scoop will take in air. The fact that they draw in fresh air from outside instead of hot under hood air means they will increase power. Virtually every car built today draws air from inside the fender or under the front bumper and through a long duct to accomplish the same thing. Not as cool looking as the old hood scoops from the classic muscle cars but just as effective.

This is the one for me.

Ah, Driver 2, thank you.

Nice i got 2 68 buick rivieras one is a gs i put a 455 in it about to put a 455 75 riviera engine in the other one lots fun driving

Watching this reminds me of the secret car of Chicago on 2001 Driver 2 PS2. Sure it's this car.

70 BUICK GSX

Beautiful car! The ultimate Buick GSX. AND you can get a clone oh I’m sorry a tribute. For a whole lot cheaper! Who cares it’s not a real one? If I had the real one I’d be afraid to drive it,..let alone take her down a dirt road. People just love this car Saturn yellow or otherwise.

The XX, those in the know...understand.....under...stand!

Most have no Idea what Saturn is...love Buick...hate saturn!

Out of all the cars in the collection that’s the one you take interesting

"An iron fist in a velvet glove"

yes stage 2

I liked the film "Crime Story 1986" and like "Classic car" their are format together .

❤❤❤❤

I didnt know air stopped flowing at the middle of the hood lol.

Torque Monster

horsepower and torque are probably sandbagging hahaha potent car. Love that cannery yellow.

Most beautiful car ever. Or was the white one??? Only two colors?

Apollo white and Saturn yellow ready for take off Houston.

the heads make the power on this car along with other things....it's 360 horse to the ground..... that's a 400 plus horse engine for a fact....you don't make 510 lbs of torque unless it's powerful..... extremely cool car.

I'll take it.

Rare Car! Can't believe that it only had a two bolt main and a 10 bolt rear end. Kind of stupid for GM at that time.

Pretty car. I don't think I ever saw one on the street. I've seen a few Gran Sports, though.

Pity the Stage 2's top end & Stage 3's 4-bolt block weren't sold. And the Stage 4? Buick would've been the king.

Back then that would be a real mans car,but as I was literally a baby I couldnt comment..

I'm a Mopar man but the 70 Buick GS/GSX 455 Stage 1 is probably my favorite muscle car of that era produced by any of the GM divisions. One reason is because you never see them. SS Chevelle's and GTO's are a dime a dozen compared to these rare beasts. The only disadvantage they had was the 2 bolt mains and thinwall block casting. They were known for cracked engine blocks... usually in the lifter valleys. Kevin is absolutely right about that. The thinwall casting made the Stage 1 455 about 150 pounds lighter than a Chevy 454 big block but it also really affected the durability of these engines. Awesome road car and very fast but really not the ideal car for drag racing on a regular basis. You were better off with an LS6 Chevelle for that if you were a GM guy

wow

Ten bolt rear axle--- go figure... Olds 442 had the 12-bolt axle, the W27 version.

Regular Stage 1 Skylarks were VERY fast cars, GSX, HOLD ON!!!

Only the 68 Ram Air II Firebird would beat it...love the GS and the GSX!!!

A buddy of mine came across one of these way back in the woods rusting away. The rumor in the area was that the owner in the 70s or 80s had driven it way back in the woods and it got stuck.

Buick.....gs x ...............HEMI KILLER

I had one in white...

Best believe if Buick was to ever bring this back. They gonna fuck the game up

I rushed to the nearest Buick dealer and asked "Where are all the RWD V8 cars? Where?" All they said is "Oh, no, all we make are FWD SUV's". Egads I had to go to a German sedan car for RWD. I think all the remaining RWD sedans are German, even the Chryslers

Have a model I built of this exact color car!! Awesome Buick and didn't they have a 390 Horsepower version of the 455??
